Very very predictable, including the post credit scene !!!

I like movies that are aware of what they are selling... without [any] greater aspirations than to make people laugh and that's it.

Tells a fascinating and unsettling true story, and does so well, without pretending to have all the answers.

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.
